Someone had to make the conscious choice to make it do that, then add the code for it — I’d love to know what their rationale was. I find it difficult to imagine how they thought it’d make things better, and how they could have missed the downsides of it.

I think it’s something they really should fix, because it screams “poor judgment”, which gives a bad first impression of their work.
